A second‐order surface‐emitting distributed feedback organic laser using 4,4′‐bis[( N ‐carbazole)styryl]biphenyl thin film as gain medium is fabricated and tested in the quasi‐continuous‐wave (quasi‐cw) regime by A. S. D. Sandanayaka, C. Adachi, and co‐workers on page 834. The device shows superior lasing properties with a low threshold and still operates properly at a repetition rate as high as 8 MHz. This represents the best performance ever reported among quasi‐continuous‐wave organic solid‐state lasers.
